Device Overview

Summary

The MIC23150 is a high-efficiency 4MHz 2A synchronous buck regulator with HyperLight Load® mode. HyperLight Load provides very high efficiency at light loads and ultra-fast transient response which is perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors. The tiny 2mm x 2mm Thin DFN (TDFN) package saves precious board space and requires only three external components.

The MIC23150 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2µF that enables a total solution size, less than 1mm height.

The MIC23150 has a very low quiescent current of 23µA and achieves a peak efficiency of 93% in continuous conduction mode. In discontinuous conduction mode, the MIC23150 can achieve 87% efficiency at 1mA.

The MIC23150 is available in 8-pin 2mm x 2mm Thin DFN package with an operating junction temperature range from -40°C to +125°C.
